Когда я обновил библиотеку @ nest / swagger до версии 4, произошла эта ошибка: 

(node:16134) UnhandledPromiseRejectionWarning: Error: A circular dependency has been detected (property key: "customer"). Please, make sure that each side of a bidirectional relationships are using lazy resolvers ("type: () => ClassType").

Класс моей модели выглядит так: 

@Entity()
export class Job {
.
.
.
    @ManyToOne(type => Customer, customer => customer.jobs)
    @ApiProperty({ type: Customer })
    customer: Customer;
}

Решение, которое работало для меня, состояло в том, чтобы объявить в @ ApiProperty () тип с функцией стрелки , как показано ниже: 

@Entity()
export class Job {
.
.
.
    @ManyToOne(type => Customer, customer => customer.jobs)
    @ApiProperty({ type: () => Customer })
    customer: Customer;
}
...
